The map is less interesting to me since I'm a non-Spaniard (population density?), but the categorizations and spending volume over time is fun to see. Groceries are shown in blue, gas stations in yellow, fashion in pink, and red in bars and restaurants. During the day, you see people filling up the tank, and then as evening comes, the city centers and coast lights up red.

– the mid afternoon spike in the red graph, is presumably the siesta?
– it looks as if late night/early morning dining and drinking is restricted to the major cities and the coast – perhaps some ex-pat and tourist influence here?

It would be very interesting to compare this to other countries like the UK who insist on working through the post-lunch slump :)
